Board Fit and Pitch Reality
The 10129381-920001BLF: The unshrouded profile means the pins are exposed after soldering, so the mating half must provide the alignment shroud or keying. 20 positions across two rows at 0.100" row spacing — the board layout is a 2×10 grid.
Gold Flash: What It Means for Field Life
The mating contacts carry 1.00µin gold over copper alloy — a flash plating that prevents oxidation during storage and initial mating. For a field-service harness that gets cycled quarterly, the gold flash is adequate — the limiting factor will be the tin solder tail, not the mating face.
Current and Voltage Ceilings
The UL94 V-0 thermoplastic housing keeps the connector safe inside equipment enclosures requiring flame-rated components.
The base product number 10129381 covers multiple position counts and plating options.
